The needle of system 216X7 has an acute round point for working woven and knit fabrics. It is used in industrial lockstitch and general-purpose sewing machines. Suitable machine classes are found, among others, at Singer (classes 133, 133 - K 13, 133 - K 14, 133 - K 18) and New Long (classes DD, DP, DD - 5, DP - 5).
The available needle sizes are used, among others, for very heavy, multi-layer materials such as webbing, tarpaulins and upholstery composites. As sewing thread, a matching thickness is usually recommended depending on the needle size chosen, e.g. from Amann Serafil (polyester) or Rasant (polyester/cotton); for heavy-duty use, a bonded nylon thread.
